FLEXIBLE SHAFT-COUPLING.

Application filed December 8, 1914.

To all whom it may concern:

Be it known that we, WILLIAM P. B. HABI- lLTON and Hnxn'r Voonnsoxo, citizens of the United States, and residents of the city of Jersey City, in the county of Hudson and State of New Jersey, have jointly invented certain. new and useful Inn-movements in Flexible Shaft-Couplings, of which the following is o specification. n

One object of our invention is to pronde a. means for detachably coupling the driving end of one shaft with the driven end of another shaft, and at the some time insulating the one from the other, even though the shafts be running at high and the coupling be subjected to a maximum of stress.

Another object of our invention is to provide a detachable insulating shoi'thoupling which will be adaptable for high speed or a, maximum of stress and which will he in operative connection although the axes of the coupled shafts very in a slight degree from a. position of axial alinement and even though the axis of the one shot; intersect the axis of the other at o. slight angle near the junction of the shafts.

Another object of our invention is to provide a detachable shaft coupling that will produce a minimum of noise and vibration when in operation and which will be subject to a. minimum of wear on the connecting ports and require little or no lubrication.

In the accompanying dmwings,Figure 1 is a detached perspective view of the coupling constituting our invention: Fig. 2 is a.

, side elevation of the coupling showing the parts assembled in operative connection Fig. 3 is an end elevation of one of the members of the coupling; Fig. 3" ise bottom view of the member shown in Fig. 3 and Fig. 4 is an end elevation of what we term the key disk of our coupling; Fig. 4 is a bottom edge view of the part shown in Fig. 4; Fig. 4" is a side edge View of thepart shownin Fig. 4-; Fig. 5 is a. side elevation of the key disk showings modified form of construction of the same.

Referrin tothe said drawings, on each of thesha s A and A is mounted a coupling member composed of collars B and B which form the hubs of the disks C and C The collars B and B are fixed against rota.- tion on the shafts A and A by meens of key sets and they may be sd3usted longitudi- Speciflcation of Letters Eatcnt.

nally on the shafts A and A by means of binding screws 01'. The face of each of the disks C and C is provided with diametri col iug, hut inasmuch the two coupling members are substantially identical in con struction, the lug is shown in the drawings on only one of the disks as indicated by the letter 6.

For the purpose of locking the two side members in operative connection We provide a key disk F which is constructed as follows: Two rectangular plates 5- of fiber or other electrically insulating material are each provided with a, longitudinal slot or groove y' of proper Width to engage the lugs c and siide eesily thereon. These plates are contained in slots one in each face of the key disk F which may be of metal, and the exposed surfaces of these plates are preferably flush with. the faces of the latter, although they project or extend therefrom to a, slight extent. The letter construction is: shown in Fig. 5. The plates 1'. thus form a lining for the slots in the face of the k'ey dish F in which they are inserted, and prevent the lugs e from coming in contact with the metal of the key disk F. In the form of construction in which the exposed surfaces oi the plates 3 are flush with the faces of the key disk, it is desirous that the slots 3 he of a depth lcss thon the height of the lugs 15 so that a space will intervene between the feces of the coupling members and the metal surfaces of the key disk even though the lugs loc inserted in the slot 5 to their full extent. If, however, the exposed surfaces of the plates zlhe allowed to extend beyond the meta faces of the key disk the depth of the slots j may be as great or even greater than the height of the lugs e.

Theplntes i are so located in. the faces of the key disk Ethel: the slots j Will be at Such a. condition need not, however, hecoindifl'erentiate the dimensions of the coupling members or of the lugs c in which event the dimensions of the slots of the key disk may be differentiated accordingly.

It will be seen that in this construction the maximum resisting power of the ma -terial which insulates the coupling members from one another is utilized, and that, although the axis of one shaft be out of alinement with the axis of the other and even though the axes of the shafts intersect at a slight angle near the junction of the shafts, the coupling members are still insulated from one another and the coupling is still operative. It will also be seen that even though insulation is not desired or necessary, the device nevertheless possesses the advantage of havingJts bearing surfaces constructed of metal and fiber working upon each other, with a consequent great power of resistance to wear, lack of necessity for lubrication and a minimum of noise and vibration.

It is realized that the relative position of the lugs and slots may be reversed. that is. the lugs may extend from the key disk and the slots may be cut in the coupling members without departing from the spirit of our invention. In that case the lugs should be located on the disk at right angles to each other, and the slots in the coupling members should be diametrical, and the fiber should be l'ocated in the latter.
